To all whom it may concern-.-

' Be it-known that I, FRAN JfSIKoRm'snY, a citizen of the United States, residing atj Chicago, in the county of-Cook and State'of' Illinois, have invented certain new and use;- ful Improvements in Collapsible Screens or Ventilators, of which thefollowingiis a specification.

This invention relates to an extensible window screen or ventilator of the type comprising a frame filled with suitable screening. material and adapted to have its ends engaged in the grooves of a window casing'beneath a window. With the screens of this type heretofore known, it has been-- necessary to slide the sections endwi'se with relation to each otherin inserting or with drawing the screen. Inasmuch as said screens are usually cheaply made structures,

it is oftendifficult to slide the sections rel ative :to each other'particularlyi in" damp weather when the usual tongue and groove connections between the section's. become swelled. v

It is a general object of my invention to produce an extensible screen which-may be, readily adapted for any width of window and which may be readily withdrawn from or inserted into the window without the ne- Cessity of sliding the sections of the screen endwise in relation to each other. Thisfgenoral object I accomplish by providing means which allow not only a relative longitudinal adjustment of the screen sections but also permit of the relative pivotal movement of the sections and it is this pivotal movement which is utilized in the insertion or withdrawal of thescreen. V Another object of the invention. is to provide means which.normal'lyrholds the sections against relative" longitudinal movement and tends to hold the sections in parallel relationship but which is yieldable to allow the relative pivotal movement of the sections necessary to the insertion and with-' drawal of the screen. l

Further objects, and objects relating to I the details of construction of the device will be fully set forth in the following descrip tion.

The

brackets*3.-and4 are located on the upper v and lower frame members 5 and 6,1-espectively, of'the scr een section 1 at'the inner end thereof, and are secured to said frame members by any suitable fastening means,

' The'brackets 3 and l are preferably made comprising a baseportion- 8 having angular flanges 9 and-'lOalongits upper and lower 1 of'sheetimetal, and in the present instance each consists of the single piece of metal edges which overlie the edges of the-frame piece. of the Y other screen. section.- The flange 9 is located at the'outer edge of the screen frame and one end of said [flange projects beyond the end of the frame section and is provided with an angular extension 11 lying in a vertical plane along theisideface of the frame bar of the other screen section.

The screen section 2 slides in a guidewayprovided by thefiang'es 9 and 10 and the extensions 1 1' of the two br'ackets,-a1idinasmuch-as V the extensions 11 are offset with relation tothee bases 8. of the brackets the screen sect1on2 may have a pivotal or swinging movement around the end of the screen" section 1 in .tion 8 is provided screen section. The flange 10, lying on the inner side of the frame member 5 isbent upon itself about half its length at 13 (Fig. 8) so as to engage between the frame member and the retaining strip whichalso holds thescreening in place. The opposite flange 9, together with the portion 13 of thefiange 10, serves as a guide for the fraineof the screen section 2. Two lugs 14 and 15 formed on the extension 11 otthe bracket serve to hold a coiled spring 16 tightly in place ,"tliereon; one end 17 ofthe spring resting on .the extension, the other end 18 thereof eX- tendin substant1all in a llOI'lZOIltttl. J'lane a screen, section. I

,The extension 11 of the bracket is made integral with the projecting portion-0t the flange 9, hence the base portion Sand the inner edge of the extension 11 lie in substantially the same vertical plane, (Figs. 3 and and bent to form a hoolrl?) to engagewith Consequently when pressure is applied on the side opposite. the springs, the screen sections will collapse between the baseportion 8 and theinner edge of-the extension 11.

,The operationof the device is as follows: To adjust the screen sections to the length desired, first raise the hook 19 or" the spring '16 and place it over the flange9, as shown in Fig.5. Then adjust the. screen sections desired. When the adjustment of the screen section is completed, place the spring hook 19 ontop of the other screen section,

1 the spring pressure causing the point of the hook to sink into the frame member (Fig. 2), thus tightly locking the sections together. Should it be desired to removethe screen as a whole from the window, grasp the screen near the middle'thereof and exert a lateral pull.

the resistance of the springs 16 mountedon the brackets and the screen collapses in the middle portion thereof and is readily removed from the window. (See Fig". '1.)

' While I have herein disclosed the presiderable particularity for'the sake of clearness, I recognize that various alternatives.

will occur to persons skilled in this art, and I, therefore, do not confine my invention to the present disclosure, but aim to cover in the appended claims all modifications and equivalents falling within the scope of the inven' tion. x
